Episode 7: Roudor Biscuits

In this episode of the Biscuit People Podcast, we are offering a new perspective that goes beyond simply focusing on the product or packaging in isolation. We explore how combining both aspects can lead to better preservation, improved consumer satisfaction, and cost-effective solutions

Spotlight on Saint-Michel’s Roudor Butter Biscuits

At the heart of our discussion is the iconic Roudor butter biscuit from Saint-Michel, a beloved treat in France. These rich, flavorful biscuits, packaged in sets of three within a metallized film, represent a common yet complex scenario for packaging engineers. From oxidation risks due to high butter content to micropunctures caused by sharp biscuit edges, Roudor serves as the perfect case study for shelf life optimization.

Hermeticity: The Key to Long-Lasting Freshness

Hermeticity plays a vital role in maintaining product integrity. In this episode, our experts delve into:

• Challenges of maintaining hermetic seals: How product shape, crumbs, and surface texture can compromise packaging.
• Innovative testing methods: Discover how burst and leak tests accurately detect micropunctures and evaluate film durability.
• Understanding the science of micropunctures: How even tiny defects can allow moisture and oxygen to enter, accelerating product deterioration.

Innovative Packaging Solutions for Difficult Products

We discuss strategies to overcome these challenges, including:

• Introducing softer inner layers to absorb the sharp edges of biscuits and reduce puncturing.
• Using metallized films for enhanced barrier properties, even in challenging conditions.
• Balancing cost efficiency with improved shelf life to meet diverse market demands.

Shelf Life Challenges in the Biscuit Industry

The Roudor biscuit case study illustrates several critical points for manufacturers:

• Oxidation risks: With 30% butter and eggs as key ingredients, Roudor faces challenges from oxidation and rancidity, particularly in tropical climates.
• Moisture control: Micropunctures in the packaging film increase moisture uptake, impacting texture and taste.
• Consumer experience: Striking a balance between robust packaging and the desired texture and crumbly nature of the biscuit.
